Des is a 16-wheeled Feistel structure cipher with a packet length of 64 bits, a 56-bit key to encrypt a 64-bit plaintext string, and a 64-bit cipher string. Where the key is 64 bits, the utility is 56 bits, and the other 8 bits are used as parity. The process of encryption is the first 64-bit plaintext group initial replacement, then the left and right two parts after 16 rounds of iterations, and then the cycle shift and transformation, and finally th

The last introduction uses Xenocode PostBuild for. NET to confuse the encryption source code to ensure the software security, this article will discuss uses the Eziriz. NET Reactor to confuse the source code of the encryption software, to share the NET Reactor use method for the user who has never used the

I have long wanted to write an article about using a USB flash drive instead of a dedicated dongle to encrypt software that does not require high encryption. Article When I visited the Internet today, I accidentally saw this blog post, which was exactly what I wanted to write. So I reprinted it here: General USB flash drives do not provide encryption functions.

General USB flash drives do not provide encryption functions. Although the shape of USB flash drives is similar to that of dongles, they are completely different internally. USB flash drives are just a memory chip and a simple ancillary circuit, currently, smart card dongles have a separate CPU or encryption chip, which can execute rather complex encryption algor

In software encryption protection technology, a common protection method is license authorization based on hardware fingerprint. This article will introduce the specific hardware fingerprint acquisition technology in detail and provide a demo source code program. Hardware fingerprint encryption means that after a user obtains and installs the

Now let's take a look at the process of guarding the secret folder encryption software: Step 1: Search the Security folder encryption software in the browser, find the resources and click the download installation. Step 2: Open the Security folder encryption

How to choose good encryption software? In fact, in the Win7 system has a U disk encryption security function--bitlocker.

PGP is currently the best and most secure encryption method. However, because some of the technologies used by PGP are exported by the National Security Department of the United States (such as AES 256bit), the Chinese version has never been released. PGP is currently the best and most secure encryption method. The Representative Software in this regard is

Security is another part of education for enterprises. Most enterprise email systems do not require the e-mail security level provided by PGP or built-in public key encryption. Endurer Note: 1. PGP-pretty good privacy is a mail encryption software based on the RSA public key encryption system. When someone needs to se
